. citizen of the United To all whom itwmay concern:

Be it known that I,'Enson C. .CovER'r, a States, and a resident of .NcwKensington, county of lVestinoreland, State of Pennsylvania, haveinvented a new and useful Improvement in" Car Roofs, of which thefollowing is aspeci ficai on.

My and has for its principal objects to secure the roof sheets at thecaves in such-manner as to eflcctually exclude the weather and stillpermit the roof sheets to accommodate themselves to the weaving of thecar; to

eliminate the chance of having careless workmen nail thereof sheets tothe side of lh car; and to. secure other .advantages hereinafterappearing. The invention consists principa ly in securing a flexiblenailing strip to the end ofthe' roof sheets in such a way as to permitthe roof sheets to inove relative to the roof sheathing. It

also'consistsiin forminga flexible'joint be- 7 tween the roof sheet andthe nailing strip;

it also consists in-providing a longitudinal.

recess at the edge of. the car to accommodate the joint between the roofsheets and their nailing strips; 1t also consists injthe con- 1 formspart of this specification, an

structions an arrangements of parts,.,her'einafter described andclaimed. In. the accompanying drawing, which wherein wherever crossseclike symbolsfrfer tov like parts they occur, Figure 1 is averticaltion of the upper edge of a car embodying myinvention; Fig. 2 is aperspective v1ew of a roof sheet having a nailin strip connected theretoin accordance wit my invention; Fig. 3 is a perspective view of aflashing strip; Fig. 4 is a sectional view of the end portion ofa roofsheet-with a. nailing strip secured thereto, said nailing strip beingswung out substantially in the plane of Y the sheeti- Ihe car comrisesaside late 1 roof sheathing 2, side sheathing 3, and a fascia;

4, which are made of-wood, and, except as otherwise noted herein,

conform to ordinary practice. llHllfllly' 'tlle top surface of the sideplate is flush with the upper surface of theroof sheeting, or the sideof the roof sheathing is flush with the outer surface of the side plate.In the present construction, however, a longitudinal recess 5 is formedin the woodwork at the upper longitudinal invention relates to metal carroofs,

im tied by. the

edge of the car. As illustrated in Fig. 1, this recess is formed byterminating the roof sheathing flush with the inner face of the fasciaand mounting said fascia with its upper surface lower than the uppersurface of the roof sheathing.

Resting upon roof sheathing are metal roof sheets 6 which are connectedat their sides by transverse joints or seams 7 of any suitable typewhich I will permit relative, movement of the sheets. The outer endportion 8 of each roof sheet is rebent on its under side and the rebentportion is rolled -or formed into an open cylindrical socket,

the open gap being smaller than the diameter of the socket. The portion9 of the sheet im- Inediatelv adjacent to the line along which it isrebent is turned downward slightl ,to

form a drip edge. Under normal conditions,

the socket portion of the sheet lies in the longitudinal recess at theedge of the woodwork bnt at a. distance from the roof sheathingsufiicient to permit the roof sheets to .inove' toward the ridge.

Interlocking'with the socket of each roof sheet is a curled or rolledrib or head IO which is formed on the upper margin of a sheet or strip11 of metal hereinafter referred to as the nailing strip. The lowerportion of" this nailin g strip'is nailed fiat? wise to, the fascia andits lower edge is pro vided witha narrow flange 12 adapted to be driveninto said fascia. In order to permit the nailing strip to move inwardlywith the roof sheet, the upper portion of the outer face of the fasciais beveled or tapered ofl, as illustrated at 13 in Fig. 2.

In consequence of'the arrangement above described, each roof sheet issecurely fastened to the substructure and at the same tiinetis free toaccommodate itself to the various distortions of the car. Movement ofthe sheets longitudinally of the car is per.- mitted by the fact that.the members of the fastening joint are free to slideor telescope; andmovement transversely of the car is persprlnging of the nailing stripsIn connection xvitlf'tlrefact that the oint is I of th'eliingeorflcxihletype. Thesemovements and an conilnmitions thereof are readilyaccommodated wilhout diseiigaging the roof sheets frmn their nailingsftiiips. It is desirable to linfetthe longitudiip'l recess with aflashing strip 14 under each 'oint or seam between the rioof sheets.Preferably,

i I l the flashing fits fiatwise against the side and i said sockets,the upper portion of said last bottom of the recess and has a flangeturned mentioned sheets. being normally spared down over the edge of thefascia. So, too, it is desirable to protect the ribs or seams 7 by capswhich have downwardly extending members 16 that are secured at theeaves. Obviously, my device admits ot considerable modification withoutdeparting .trom my invention, and therefore I do not wish to be limitedto the specific construction shown and described.

.upper marginal portions rolled to to secure by Letters Patent is:

1. A car comprising roof sheets whose outer ends are rebent on theunderside to form outwardly opening sockets, and clips What I claim asmy invention and desire mounted the'side of the car and having headsinterlocking with said sockets.

2. A car comprising roof sheets whose outer ends are 'rebent on the,underside to form sockets, the part adjacent to the line of the rebendbeing turned downwardly, and

- sockets.

5. A car comprising roof sheets whose outer ends are bent to formsockets at the edge of the car and sheets of metal mounted on the sideof the car and having'their upper marginal portions rolled to fitpivotally in from the side of the car.

6. A car comprising side plates. side sheathing and roof sheathing andfascia arranged to form an angular recess, and metal roof sheets hatingtheir outer ends rehent to form sockets located in said recess, andclips consisting of sheets of metal mounted on the located in saidrecess, and clips mounted on the fascia and pro\ 'ided 'with headsinterlocking with saidsoeltets, the outermost portions of saidsheetshelng turned downwardly to partially close the openi ng'of saidsockets and form a drip 8. A car comprising side plates, side sheathing,roofsheatl'nng, a fascia, said iascla tern'nnating below'the uppersurface of the roof sheathing and having the upper portlon of its outersurface beveled, metal roof. sheets having their outer ends rebcnt toform sockets located above the fascia, and

resilient clips mounted on the fascia below the beveled portion andhaving heads inter locking with said sockets.
